IMPORTANT HIGHLIGHTS
1. RATIO & PROPORTION
KEY CONCEPTS:
RATIO: COMPARISON OF TWO QUANTITIES
A : B = A/B
PROPORTION: EQUALITY OF TWO RATIOS
A : B = C : D ⇒ A/B = C/D
IMPORTANT FORMULAS:
FOURTH PROPORTIONAL = (B × C) / A
MEAN PROPORTIONAL = √(AB)
IF A : B = C : D ⇒ AD = BC
DUPLICATE RATIO OF A : B = A² : B²
SHORTCUT TRICKS:
MULTIPLY/DIVIDE BOTH TERMS BY SAME NUMBER → RATIO UNCHANGED
CONVERT MIXED QUANTITIES INTO SAME UNITS BEFORE SOLVING
2. COMPARISON (BASED ON RATIO)
KEY CONCEPTS:
COMPARE TWO QUANTITIES USING RATIOS OR FRACTIONS
USE LCM METHOD OR CROSS MULTIPLICATION
IMPORTANT TRICKS:
IF A/B > C/D ⇒ A×D > B×C
FOR COMPARING FRACTIONS: MAKE DENOMINATORS EQUAL
3. PARTNERSHIP
KEY CONCEPTS:
PROFIT ∝ (INVESTMENT × TIME)
IMPORTANT FORMULAS:
SHARE RATIO = (CAPITAL₁ × TIME₁) : (CAPITAL₂ × TIME₂)
PROFIT SHARE = TOTAL PROFIT × INDIVIDUAL RATIO / TOTAL RATIO
TYPES:
SIMPLE PARTNERSHIP → SAME TIME
COMPOUND PARTNERSHIP → DIFFERENT TIME
